An arc-shaped concave portion 39 is provided at the lower edge of 8.

The actuator 50 has an odd-pole terminal 30.
A through-hole 53 is formed to correspond to the rotation support piece 37 provided in the above. The side wall on the trailing edge side of the actuator 50 defining the through hole 53 has a unique shape such as a cocoon-shaped cross section as shown in FIGS. A rotating wall 54 that rotates with the rotation is configured. Then, an enlarged portion of the rotating wall 54 fits into and engages with the recess 39 formed in the rotating support piece 37 on the terminal 30 side, and the recess 39 of the rotating support piece 37 and the The rotation center O of the actuator 50 is constituted by the enormous portion. The enlarged portion of the rotating wall 54 has a substantially circular cross section, the center of rotation O coincides with the center of the enlarged portion, and the enlarged portion of the rotating wall 54 and the rotation supporting piece 37 are always engaged. Have been maintained.

As shown in FIGS. 1 and 5, the rotating wall 54 is provided obliquely with respect to the plate surface of the actuator 50, and one side surface thereof is in contact with the rear end surface 55 of the actuator 50. It is one. The entire rear end face 55 is obliquely inclined. Actuator 5 of FIG.
When 0 is turned to the closed position, the enlarged portion of the turning wall 54 is at the top, and extends downward therefrom to the lower surface of the actuator 50. When the actuator 50 is rotated to the open position in FIG. 1, the rotation wall 54 is substantially horizontal, the enormous portion is located rearward, and extends forward therefrom, so that the rotation support piece 37 It is located below the distal end side of the recess 39. Further rotation of the actuator 50 in the opening direction from this state is prevented by the engagement between the rotation wall 54 and the tip of the rotation support piece 37.

Next, the terminals 40 of the even-numbered pole mounted from the rear side 12 of the insulating housing 10 have the shapes shown in FIGS. The terminal 40 has a base 41 whose height is substantially equal to the height of the terminal mounting groove 16.

In this state, the contact pieces 43 extend in the cable receiving cavity 13 in the front edge direction, and the contact portions 45 of the respective terminals 40 are aligned in a line on the front side in the cable receiving cavity 13. As a result, the contact portions 36 of the terminals 30 that are aligned in a single row rearward in the cable receiving cavity 13.
And the contact portions 45 of the terminals 40 arranged in a line on the front side, so that the entire contact portions 36 and 45 have a staggered arrangement.

As is apparent from FIGS. 1 and 5, the rotation center O is located between the row of the contact portions 36 of the terminals 30 and the row of the contact portions 45 of the terminals 40 in the cable receiving cavity 13. Is above.

It is made shorter and extends to the upper part of the row of the contact portions 36 of the terminals 30 . Insulate terminal 40
When mounted on the housing 10, the pressure-resistant piece 44 becomes an insulating housing.
Of the upper surface wall 14a forming the upper surface 14 of the ring 10
Extending in the direction of the front 11 in contact with the tip portion are so as to face to protrude to the upper rear of the cable receiving cavity 13. A relief groove 56 as shown in FIGS. 2 and 6 is formed in the rear end face 55 of the actuator 50 so as to correspond to the pressure-resistant piece 44. The relief groove 56 is formed halfway from the upper surface to the lower surface of the actuator 50, and the remaining portion without the relief groove 56 is formed when the actuator 50 is rotated to the closed position. There is a projection 57 that extends under the tip .

The groove bottom 58 of the clearance groove 56 is substantially parallel to the rear end face 55 of the actuator 50. When the actuator 50 is closed (FIG. 6), there is a gap between the tip of the pressure-resistant piece 44 and the groove bottom 58. A slight clearance 59 is formed. When the actuator 50 is rotated to the open position (FIG. 2), the groove bottom 58 is engaged with the upper edge of the pressure-resistant piece 44 to prevent the actuator 50 from further rotating in the open direction. I try to prevent it.

When the rotatably supported actuator 50 is rotated to the open position as shown in FIGS. 1 to 4, the actuator 50 stops at that position. The rotation support piece 37 provided on the terminal 30 extends forward through a through hole 53 formed in the actuator 50. With such an opening structure of the actuator 50, the cable receiving cavity 13 can be largely opened. As a result, when the actuator 50 is in the open position, the contact portion 45 of the terminal 40 is exposed so as to be visible from the outside, and the contact portion 36 of the terminal 30 is located below the rear end face 55 of the actuator 50 and is located outside. It is in a state where it can be peeped from.

The gap between the contact portion 36 of the terminal 30 and the rear end face 55 of the actuator 50 is
0 is an insertion gap 101 into which the insertion gap 101 is inserted. This insertion gap 1
01 is set to a gap wider than the thickness T (FIG. 1) of the flat flexible cable 100. Therefore, the flat flexible cable 100 is in the state where the actuator 50 is in the open state.
It can be easily inserted in the direction of arrow 102 above the contact portions 36 and 45 with zero insertion force.

When the actuator 50 is rotated to the closed position shown in FIGS. 5 to 8 after the flat flexible cable 100 is inserted, the protrusions 52 provided on both sides of the front edge of the actuator 50 are brought into contact with the stopper pieces 18 of the insulating housing 10. The engagement is maintained in the closed state. When the actuator 50 is rotated to the closed position, the lower surface of the actuator 50 presses the flat flexible cable 100 toward the lower contact portions 36 and 45, and the contact portions 36 and 45 and the flat flexible cable 100 are pressed.
Are engaged with an appropriate contact pressure and are electrically connected. 5 and 6, the flat flexible cable 100 is not shown, but the lower surface of the actuator 50 and the contact portions 36, 4
5 between the flat flexible cable 100

43 is elastically deformed downward, and an appropriate contact pressure is obtained by its elasticity.

The elasticity of the contact pieces 35 and 43 is
Tip 38 of the pivot support member 37 of the 0 and the actuator 50
And the tip of the pressure-resistant piece 44 of the terminal 40.
Both the end and the engagement portion of the projection 57 of the actuator 50 are cooperatively received. That is, the contact piece 35,
The elasticity of all the terminals 30, 40 and the actuator 5
Thus, stress is not concentrated on one of the rotation support piece 37 and the pressure-resistant piece 44 by being distributed to the engagement portions of No. 0. This is effective in preventing deformation of the rotation support piece 37 and the pressure-resistant piece 44, and in avoiding early wear of the actuator 50.

The enlarged portion of the turning wall 54 of the actuator 50 and the recess 39 of the turning support piece 37 of the terminal 30 are always engaged in the turning range between the open position and the closed position of the actuator 50. . Therefore, the operation of rotating the actuator 50 to the open position and the operation of rotating the actuator 50 to the closed position can be stably performed.

The configuration in which the center of rotation O formed by the engagement between the enormous portion of the rotating wall 54 and the recess 39 is located above the row of the contact portions 36 and the row of the contact portions 45 The contact pressure on the part 36 side and the contact pressure on the contact part 45 side are easily balanced. Therefore, the contacts of the flat flexible cable 100 and the corresponding contact portions 3
Improve the reliability of all the connection parts of 6, 45.

When the actuator 50 is in the open position, the rotation support piece 37 of the terminal 30 is
The configuration extending to the front side through the zero through-hole 53 is effective not only for greatly opening the cable receiving cavity 13 but also for reducing the size of the flat flexible cable connector in the front-rear direction. In addition, while securing a wide insertion gap 101 for the flat flexible cable 100, it is possible to contribute to a reduction in the height of the flat flexible cable connector.

In the embodiment described above, the rotation support piece 37 is provided on the terminal 30 mounted from the front side of the insulating housing 10, and the pressure-resistant piece 44 is provided on the terminal 40 mounted from the rear side of the insulating housing 10.
